Abstract
Official abstract text for this publication.
In a testing overspeed protection system: a) on receiving an order to start a turbomachine, an electronic regulation system (ERS) of the turbomachine sends an order to a control circuit of a fuel cutoff member to close the fuel cutoff member or to keep it in the closed position; b) the closed state of the FCM is verified on the basis of information transmitted to the ERS and representative of the position of the FCM; c) if the result of the verification in b) is positive, the ERS sends an order to the FCM control circuit to authorize opening of the FCM and enable the starting procedure to continue; and d) if the result of the verification in b) is negative, the ERS issues fault information concerning the overspeed protection system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of testing a system for protecting a turbomachine against overspeed during starting of the turbomachine, the protection system including a fuel cutoff member and a circuit for controlling the cutoff member that is connected to an electronic regulation system of the engine to cause the cutoff member to close to interrupt or reduce the supply of fuel to a combustion chamber of the turbomachine in response to overspeed being detected, the method c…
